AEP Maximum Destinations Per Sandbox — 100 (System-Enforced)

constraint.aep-destinations-per-sandbox-100 ↗

Adobe Experience Platform enforces a hard limit of 100 destination instances per sandbox. System-enforced — AEP blocks creation of the 101st destination. Organizations building multi-channel activation architectures with AEP Real-Time CDP must account for this ceiling when designing their destination catalog. Multi-sandbox strategies become architecturally necessary for enterprise organizations whose activation surface exceeds 100 distinct endpoint connections (e.g., regional separation, business unit isolation, channel diversification across email, paid-media, CRM, streaming, analytics, and personalization destinations).
